BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 645,616, dated March20, 1900.

Application filed February 28,1899. Serial No- 707,236. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES J. ANDERSON, a citizen of the United Statesof America, residing at Pittsburg, in the county of Allegheny and Stateof Pennsylvania, have inventedcertain new and useful Improvements inBrick-Machines; and I do hereby declare the following to be a full,clear, and exact description'thereof, reference being had to'theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in abrick-machine.

The invention has for its object the provision of a machine for makingfuel-briquets in the form of bricks, being simple in construction,strong, durable, and comparatively inexpensive to manufacture.

With the above object in view the invention finally consists in thenovel construction, combination, and arrangements of parts, as will behereinafter more specifically described in detail.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference designate like parts in the several views, inwhich- Figure 1 is a side view of the complete machine. Fig. 2 is aperspective View of the main shaft and its cams removed from themachine. Fig. 3 is a front elevation of a portion of the frame, showingone of the camgrooves for operating the molds. Fig. 4 is a top plan viewof the complete machine; Fig- 5 is a side view of the rotary mold,partly in section. Fig. 6 is a front view of the same, partly insection. Fig. 7 is a side view of the same, showing the lever forrotating the same. Fig. 8 is a perspective view of thecompressing-plungers.

Referring to"the drawings, the numeral 1 designates the frame of themachine, said frame having arranged at its rear the rotatable shaft 2,upon which are secured the cams 3, 4, 5, 6, and 7, which operate themachine. The outer cams 3 and 7 have arranged thereon the straps 8 and9, which are connected to the levers 10 and 11 by means of the rods 12and 13 and links 14 and 15. The upper end of the said levers 10 and 11are connected to the sliding plates 16 and 17 by means of the links 18and 19. These sliding plates have each formed therein the three openings20, 21, and 22 forthe reception of the material as it passestherethrough into the molds. The frame'l has suitably journaled thereina shaft 24, upon which is mounted a rotatable wheel 23; ranged therein aseries of molds in sets of threes. The molds are each provided with themovable bottoms 25, which are or may be formed integral'with fingers 26of the discharging-bar 26. This bar 26 extends outwardly on each side ofthe Wheel23 through the slot 27', as shown. These extending ends areshown at 27 and engage in an eccentric groove arranged on the inner faceof the frame 1, as shown in dotted lines in Fig. 1.

The plungers 29 for the molds are-attached to thevertical movablestandards 30, which have an oblong opening formed in them to straddlethe shaft 24. The levers 31 are pivotally attached to the lower ends ofthese standards, and the opposite ends of these le- This wheel hasarvers are secured upon a shaft 32, extending under side of the slidingbar 34, said bar being in contact with the cam 4. The strap 35 uponthecam 6 is also attached to the said sliding bar by means of'a rod or pin36.

Openings 37 are formed at four points upon the periphery of themold-wheel, and engaging with one of these openings is thespringactuated rod 38,'which is attached to the pivoted upright .lever39, said lever being operated by the cam-wheel 4 to disengage the end ofthe spring-actuated rod from the opening of the wheel at the propermoment. Upon one side of the mold-wheel is arranged the pins 40, whichengage with a hooked bar 41, said bar being attached to the lever 42,which is secured fast upon the same shaft 43 to which the aforesaidlever 11 is secured.

In practice a hopper for holding the material is placed above or overthe opening in each of the sliding plates, thereby filling saidopenings. When power is applied to the camshaft, the said cams transmitthe following movements to the parts: First, the cams 3 and 7 in theirrotation cause the sliding plates to move so that the openingscontaining the ICO material shall register with one another directlyabove one set of molds of the wheel. These plates then remainstationary, and the material drops down into the mold. The plungers thendescend, compress the material in the mold, and then return to theirformer po sition. The sliding plates then return to their normalposition, and at the same time in which the lever controlling the saidsliding plates moves back to its normal position the lever 42 also movesbackward until one of the pins engages with the shoulder or hookedportion of the bar 41. The rod 38 then disengages with the opening inthe face of the mold-wheel by the action of the cam-wheel 4. The saidbar 41 then comes into action and causes the mold-wheel to rotateonequarter revolution and then stops with the next mold in position.This operation is then repeated through the rotation of the cams. Theprojecting ends of the discharging-bar in the molds traversing thecam-groove in the frame cause the said movable bottom in the molds todischarge the bricks from the mold on the under side of the wheel. Bythis device the bricks are formed at'a rapid rate and discharged.

Having thus fully shown and described my invention, what I claim as new,and desire to secure by Letters Patent, is- I 1. In a brick-machine, asuitable frame provided on the inner face of each of the sides with aneccentric groove, a shaft journaled in one end of the said frame, aseries of cams 3, 4, 5, 6, and 7, mounted thereon, a rotating wheelcarrying a series of molds mounted in the said frame and operated by oneof the said cams, plungers operating in the said molds and operated byone of said cams, a movable bottom arranged in the said molds, and adischarging-bar adapted to operate the said bottom when the ends of thesaid bar engage in the said groove during the rotation of the wheel,substantially as described.

2. In a brick-machine, a suitable frame provided on the inner face ofeach of thesides with an eccentric groove, a shaft j ournaled in one endof the said frame, a series of cams 3, 4, 5, 6, and 7, mounted thereon,a pair of sliding plates provided with suitable openings operating uponthe top of the said frame, connections between the cams 3 and '7 and thesaid plates for operating the same, a rotating wheel journaled in thesaid frame and carrying a series of molds adapted to be brought intoalinement with the openings in the said plates, operating means for thesaid wheel, plungers operating in said molds and operated by one of saidcams, a movable bottom arranged in the said molds, and a discharging-baradapted to operate the said bottom when the ends of the said bar engagein the eccentric groove during the rotation of the wheel, substantiallyas described.
